Application filed Ju1y12, 1922: Serial No.'574=,428.

T 0 all wlzomt may concern:

' Be it known that I, SENECA Monnrs PIKE, a citizen of the United States, residing at Troy, in the county of Rensselaer andState of New York, have invented new and useful Improvements in Thermometers, of which the following is a specification.

Reference may be had to the'aceompanying drawings, and the reference characters marked thereon, which form. a part of this specification. Similar characters refer to similar parts in the several figures therein.

The principalobject of the invention is to protect the liquid-containing tube of the thermometer, and provide means for detach ably mounting the thermometer upon a rod .or the like, such as one of the bars of an oven shelf. 7

Other objects will appear in connection with the following descript on. 1

Fig. 1 of thedrawings is a view infront elevation of a thermometer made in accordance with my invention.

Fig. 2 is a side view of the same mounted upon a supporting rod. v

Fig.3 is a cross section ofthe same taken on the broken llne 33 in Fig. 1.

Referring to the drawings wherein the invention is shown in preferred form, 1. is a liquid-containing tube terminating atthe lower end in a bulb, 2, containing mercury or the like suitable for thermometric use.

The tube is mounted upon a; channeled frame, 3, within the. channel in the frame in position to be protected-by the side walls, a,

of the frame the tube being thus mounted in,

' the usual manner by wire straps or clips, 5.

Attached to the lower end of the frame, 3,- is an L-shaped bracket, 6, the lower end of which forms a horizontal flange, 7, which extends opposite the lower end of the channel in the frame, 3, and opposite the bulhtube, 1, in position to protect the bulb-end of the tube; v

The side walls, at, of thechanneled frame, 3, are tapered upwardly from their lower ends wherat they are of sufficient widthto properly protect the bulb-end-of the tube 1.

, The lower ends of the side walls, 4, are

be a rod of an oven shelf such as is comthe like.

formed with alined' notches, 8, adapted to engage a rod, .9, or the like, which rod may The horizontal flange, 7, of the bracket, '6, is provided with a screw-threaded aperture, 10, adapted to receive a screw, 11,in position for the screw to engage the rod,

9, seated in the notches, 8, whereby the thermometer frame can be securely attached to said rod, 9. y

The rod-engaging end of: the screw, 11, is preferably provided with an enlargement or head, 12, to engage the rod, 9.

By unscrewing the screw, 11, the thermometer framecan readily be released and detached from the rod,'9, when'theuse of Y the thermometer in the oven is not desired. The device'is readily applied to: the rod,

,9, by merely setting theinotched ends of'the slde walls, 4,.of the'frame upon the rodand then setting up the clamp the rod. I r i The widening of the side walls, 4;, in the lower end to protect the bulb-endflof the screw, 11, to securely tube, 1, makes said walls ofv sufficient width I to provide for the forming of the notehes,-8.

The frame, 3, and bracket, 6, are preferably struck up from sheet-metal, but may bemade of any suitable material adapted to withstand oven temperatures.

What I ,claim as new and desire to secure by Letters Patent is: I

1. A thermometer having a liquid-containing tube mounted withina channeled frame formed withalined notches in its side walls at one end, and screw mechanism gagea rod seated in said end notches in the side walls of the frame.

screw fitting the screw-threadedaperture in said flange in position to engage. a rod mounted upon the frame in position to enseated in said end notches in the side walls of the frame. v I

, In testimony whereof, I have hereunto setmy hand this 7th day of April, .1922. monly used in the ovens of gas stoves and SENECA Monnis PIKE,
